Flashcards: Fundamentals of Cell Biology and Physics — 12 cartões

Animal cell — key features?

Nucleus, cytoplasm, membrane, mitochondria.

Plant cell — extra structures?

Cell wall, chloroplasts, vacuole.

Mitochondria — role?

Releases energy during respiration.

Cell respiration — equation?

Glucose + oxygen → CO2 + water + energy.

Photosynthesis — equation?

CO2 + water + light + chlorophyll → glucose + O2.

States of matter — particle movement?

Increases with heat, solids fixed shape, gases no fixed shape or volume.

Solid — shape and volume?

Fixed shape and volume.

pH indicator — purpose?

Changes colour based on solution's pH.

Elements vs compounds?

Elements are one atom type; compounds are chemically bonded elements.

Mixtures — bonding?

Components are not chemically bonded.

Speed formula?

Speed = distance ÷ time.

Energy transfer — principle?

Energy moves but is not created or destroyed.
